IMPROVEMENT IN SEED-DROPPERS.

Specification forming part of Letters Patent No. 120,230, dated October24, 1871.

To all whom it may concern:

Be it known that I, J osnrn (J. BARLOW, of Quincy, in the county ofAdams and State of Illinois, have invented a new and useful Improvementin Corn-Planter Out-off; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

Figure 1 is a detail sectional view of my improved cut-off taken throughthe line m 00, Fig. 2. Fig. 2 is a detail sectional view of the sametaken through the line y y, Fig. 1.

Similar letters ofreference indicate corresponding parts.

My invention has for its object to furnish an improved cutofi" forcorn-planters and other seeders, to brush off the superfluous grainsafter the holes or chambers of the dropping-plate have been filled, andwhich shall be so constructed as not to injure or break the seeds; andit consists of the various parts of the cutoff, as hereinafter morefully described.

A represents a plate, which is placed in the bottom of the seed-hopper,and close beneath which the dropping-plate slides or is placed. B aretwo metallic plates, the lower parts of which are placed in grooves orrecesses in the middle parts of the plate or frame A. Upon the outersides of the plates B are formed lugs b, which rest upon the sides ofthe plates A, to which they are securely bolted. The upper ends of theplates B are rounded off, and have grooves formed in their inner sidesto receive the edges of the capplate or cover O, as shown in Fig. 2,thus giving to the top of the cut-0E the form of a flattenedsemi-cylinder. This form I prefer, but the form of the upper ends of theplates B and of the cap-plate 0 may be changed without departing from myinvention. Upon the inner sides of the lower part of each of the platesE is formed a pivot, D, which enters sockets in the middle or angularparts of the pieces or plates E, to pivot the said plates. The upperparts of the plates E are curved to correspond with and fit upon theinner surface of the cap 0, as shown in Fig. 1. The lower parts of theplates E incline outward and downward, and their outer edges come downto, but do not rest upon, the droppingplate, in which position they areheld by a spring or springs, F, made of rubber or other suitablematerial, placed within the cap (I, and so arranged as to press theupper parts of the plates E outward against the cap or cover 0, whichthus serves as a stop to prevent the lower parts of the plates E fromdropping down so far as to rest upon the dropping-plate. The spring orsprings F should possess sufficient elasticity to allow the plates E toyield before breaking the seed, and at the same time with sufficientstrength to hold the plates E down with the necessary force.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The arrangement of the two angular plates injuxtaposition to one another in a corn-planter, as and for the purposespecified.

2. The combination of the plate or plates 13, cap-plate G, pivotedangular plates E, and spring or springs F with each other, substantiallyas herein shown and described, and for the purpose set forth.
